Professor Guo Hong's team from the School of Materials and Energy of Yunnan University, using the university as the only communication unit, recently published a paper – Understanding the synergistic mechanism of single atom Co-modified perovskite oxide for piezo-photocatalytic carbon dioxide reduction – in the international journal Applied Catalysis B: Environmental and announced the latest meaningful progress of new energy storage materials.

In recent years, the increase in greenhouse gases has brought severe environmental crises to the world. Therefore, converting carbon dioxide into renewable fuels has become the focus of human research. Photocatalysis converts carbon dioxide into chemicals and fuels in a green, economical, and efficient way, solving various environmental problems and energy crises.

However, due to the limited energy of photocatalysis, the reduction efficiency is low, so the catalytic reduction of carbon dioxide research still needs to be improved.

Based on the current research status and problems, to achieve the sustainable development goal of carbon peak and carbon neutrality, and combined with the previous research basis, Guo's team proposed a new strategy of combining photocatalysis and piezoelectric catalysis for carbon dioxide reduction and the prepared catalyst material has excellent piezoelectric photocatalytic carbon dioxide reduction performance.

This paper offers a thorough examination of the piezoelectric photocatalytic reduction of carbon dioxide mechanism, presenting valuable insights and concepts to improve the process of piezoelectric photocatalytic reduction of carbon dioxide.

The research results have been supported by the national fundamental research and development plan, the new energy major project of Yunnan province, and Yunnan Yuntianhua Co.
